Certified diamonds, especially from independent and reputable laboratories like GIA provide authenticate report on diamond quality, whereas non-certified diamonds may have questionable origins or it may not be authentic stone. Certified diamonds have recognizable details and characteristics listed in the diamond certificates. Exact measurements, weight, cut, clarity, fluorescence, colour grade, proportions and finish grade are detailed on the certificate. With the certificate, it can be easier to recover the stone if it is lost or stolen, and if at some point the owner wishes to upgrade the diamond jewellery, it will be easier to find a similar stone with comparable characteristics.

Buying certified diamonds allows you to make informed purchases. Consumers can compare stones of similar quality to judge the best price.

Note:Diamond grading report or certificate is not same as an appraisal. The grading report does not assign value to the stone, it report on diamond quality like precise measurement, internal and external flaws, colour, carat weight and other characteristics. On the other hand, an appraisal report or certificate assigns value to a diamond or jewellery article.
